I have a pretty simple smart thermostat without many fancy features. Every Spring and Fall I tell myself I should set up some kind of system where if the outdoor weather is good enough, maybe I dial back the heating / cooling, maybe send myself a text to open windows, etc.
Small example: I normally keep my house at 72 in the summer, but if it’s up to 76 or so outside, it’d be nice if the thermostat turned off the cooling. I could manually turn it back on if I have guests over, etc.
I’m sure some of this logic would be easy to code myself, but wanted to check out what anyone else is doing first.
Using home assistant.
It’s nothing fancy, but I have phone alerts if any windows are open when the heating comes on, and I also use the average temperature inside the house as the input temperature for the thermostat (sensors in several rooms are averaged and published via MQTT to a DIYless thermostat).
My plan going forward is to add ZigBee TRVs to the radiators in each room and automatically close any that are already at or over the target temperature.
